given by
r = 3.0+ i +2.0t?j+5.0k
where tis in seconds and the coefficients
have the proper units for r to be in metres.
(a) Find v(t) and a(t) of the particle. (b) Find
the magnitude and direction of vio) at
t= 1.0 s.​

Answer 1

Answer:

v=2

Explanation:

the magnitude =5.3 and the directuon will be = north
